This page contains the walkthrough for Windwalker: The Stormchaser, one of the main missions in Just Cause 4. To unlock it you need to capture Tierras Bajas region first. Your goal is to escort a helicopter piloted by Cesar - make sure that the cargo will reach the destination in one piece.
Starting the mission
Cesar starts flying his helicopter. You start near a car - get inside it if you don't want to follow the helicopter on foot. You won't encounter any enemies here so focus on following Cesar. Soon, you will reach a location full of enemies.
Destroying the anti-aircraft cannons
During the mission, you will reach two locations where you have to destroy three anti-aircraft cannons - otherwise, Cesar won't be able to fly towards the destination. The cannons are marked on the screen. Watch out for the enemies nearby. There are multiple armored enemies and snipers so be on the move.
In the later phase, Cesar will get attacked by enemy vehicles - both ground and flying ones. An armored vehicle with a machine gun on its rooftop can be found in the location where you have destroyed the anti-aircraft cannons. This car allows you to destroy enemy helicopters and other vehicles. If you don't want to drive this car, use other means to destroy the vehicles - such as rocket launchers or the Retractor modification for your grappling hook.
After reaching the destination, the last thing you have to do is to press the button. Watch the cut-scene.
